When you hold a freshly machined stainless steel part in your hand, you notice the cold metallic touch, the subtle shine of knurling patterns, and the smooth bore from precision drilling. For procurement managers or engineers sourcing CNC turning stainless steel 304F parts, these details aren’t just aesthetics—they determine durability, assembly fit, and long-term performance.

What Is Stainless Steel 304F in CNC Turning?

Stainless Steel 304F is a free-machining version of the widely used 304 stainless steel. The key advantage is the addition of sulfur, which improves machinability without sacrificing corrosion resistance.

  • Machining benefit: Reduced tool wear and faster cutting speed.
  • Application: Automotive fasteners, medical connectors, precision knurled grips, and electronic housings.
  • Why it matters for buyers: Lower production costs and consistent quality across large batches.
CNC Turning with 304F Stainless Steel: Core Processes

When manufacturers produce custom components, they rely on different machining methods:

  1. Turning
    • Achieves tight tolerances (±0.01 mm).
    • Ideal for cylindrical parts such as shafts, bushings, and threaded inserts.
  2. Knurling
    • Creates textured surfaces for better grip.
    • Common in tool handles, adjustment knobs, and surgical instruments.
  3. Drilling
    • Ensures precise hole placement for assembly.
    • Works seamlessly with secondary processes like tapping or reaming.

Tip for buyers: Always confirm whether the supplier offers both single-operation CNC turning and multi-axis turn-mill centers—the latter can reduce lead time by 30%.

Case Study: Knurled Stainless 304F Connector

One of our customers in the medical device industry required a batch of 5,000 knurled stainless connectors. Using CNC turning with in-process knurling and drilling, we:

  • Reduced cycle time by 22% (compared to machining knurling separately).
  • Maintained a surface roughness of Ra 0.8 µm.
  • Passed 500-hour salt spray corrosion testing.

This kind of real-world performance data is critical for procurement teams deciding between materials or suppliers.

Cost Factors When Ordering 304F CNC Parts

When you request a quote, the final price depends on:

  • Material size & grade: Stainless steel 304F rod vs. bar stock.
  • Complexity of knurling & drilling: Straight knurling costs less than diamond-pattern knurling.
  • Batch size: Unit cost can drop by 40% when moving from prototype (50 pcs) to production (5,000 pcs).
  • Surface finishing: Electropolishing or passivation adds cost but improves resistance in harsh environments.

Pro tip: Ask suppliers for DFM (Design for Manufacturability) feedback before finalizing the drawing. Small design changes—like radius adjustments—can cut machining time by 10–15%.

Supplier Checklist for Buyers

When sourcing CNC turned stainless steel 304F parts with knurling drilling, look for:

  • ✅ In-house QC with CMM inspection.
  • ✅ Experience with medical/automotive standards (ISO 13485, IATF 16949).
  • ✅ Ability to provide both prototypes and high-volume runs.
  • ✅ Transparent lead time and shipping options.
